Application May 12, 1953, Serial No. 354,475

1 Claim. (Cl. 57-57) This invention relates to that class of spinning apparatus in which the spinning ring is non-rotatably mounted with respect to the bobbin and has thereon a traveler rotatably mounted on the ring and adapted to operate at high speed.

Much difiiculty has heretofore been experienced due to the excess accumulation of lint and foreign substance upon the traveler which will cause trouble and frequent breaks of yarn or thread.

My improved cleaner is so designed and shaped as to present an arcuate cleaning surface of considerable extent which is disposed closely adjacent the path of movement of the traveler and serves to effectively clean the traveler and to prevent excess accumulation of lint or other foreign substance upon the traveler. This arcuate cleaning surface is preferably used in addition to the usual cleaning wire or post which has been found to be unsatisfactory. This additional arcuate cleaning surface is preferably disposed diametrically opposite the usual cleaning wire for the best results.

My improved cleaner keeps the point of the traveler clean and decreases the end breakage between 40% and 50% on actual tests and also increases the life of the traveler and does not cut or damage the full bobbin of yarn.

My cleaner is adapted for use on any type of traveler or ring now in general use. If desired, my improved traveler cleaner may be used without the cleaning wire or post now commonly used; but the two cleaners cooperate together eifectively to keep the traveler clean at both the top and bottom thereof thus greatly increasing production without breakdowns.

The main object of the invention is to provide a cleaner for spinner ring travelers which will effectively clean the traveler and prevent excess accumulation of lint or other material thereon and which will reduce to a minimum the breakage of yarn or thread and practically eliminate shutdowns caused by excess lint or the like on the traveler.

Another object of the invention is to provide a cleaner for spinner ring travelers which consists essentially of a cleaning member so designed and positioned as to present to the area to be cleaned a narrow arcuate surface which is disposed in the path of the traveler so as to effectively clean the traveler.

A further object of the invention is to provide a cleaner for spinning ring travelers which comprises two cleaning surfaces one of which is arcuate in shape and serves to clean the upper portion of the traveler, and the other of which engages the lower portion of the traveler and presents a cleaning surface of limited extent, such two cleaning surfaces cooperating to effectively clean out the traveler.

Referring now to the drawings in which similar reference characters indicate corresponding parts Fig. 1 is a view in elevation showing a spinner ring secured within a suitable frame;

Fig. 2 is a transverse sectional view taken on the line ner well known to those skilled in the art.

Fig. 3 is a transverse sectional view of the assembly taken approximately at right angles to the view shown in Fig. 2.

Referring now to the drawings the reference character 1 designates a spinner frame which receives therein a ring member indicated generally by the reference character 2 and which has a downwardly extending skirt portion 3 and an overhanging flange portion 4. This ring is preferably split as indicated at 2a in Fig. 1. Carried by the ring member 4 is a spinner ring indicated by the reference character 6 and which has thereon an outwardly projecting flange 6a. Carried by the traveler ring is a traveler indicated by the reference character 7. This traveler is of a shape shown most clearly in Figs. 2 and 3 and is secured in place in any suitable manner. This traveler is adapted to rotate about the traveler ring at a high speed.

Carried by the spinner ring 6 and preferably secured thereto rigidly is a cleaning post 9 which may be formed of wire or other suitable material. Disposed diametrical- 1y opposite the post 9 is a cleaning member indicated by the reference character 8 which is in the form of a generally U-shaped piece of wire having its ends secured within the spinner ring 6. This cleaner member 8 is so shaped and designed as to provide an arcuate surface of considerable extent which extends a substantial distance and is disposed parallel to the path of movement of the traveler 7. This arcuate surface indicated by the reference character 8:: is disposed in close proximity to the path of travel of the traveler and serves to wipe off any excess lint or foreign matter which may accumulate on the traveler.

It will thus be seen that my improved cleaner comprises two cleaning surfaces one of which is arcuate in shape and extends over a substantial area and the other of which is in the form of a post disposed diametrically opposite the first cleaning surface and which has only line contact with the surface to be cleaned.

In the normal operation of the device a bobbin 10 extends through the ring member and is positioned substantially as illustrated in Fig. 2. The bobbin is rotated at a relatively high speed and suitable mechanical means are provided for causing a relative reciprocatory motion of the spinner ring with respect to the bobbin in a man- As the bobbin is rotated at high speed the traveler 7 is caused to rotate about the spinner ring at high speed and excess lint or other foreign substance which may accumulate on the traveler is wiped off by the surfaces 8a and the post 5 which cooperate together to maintain the traveler clean.

It will now be clear that I have provided an improved cleaner for spinning ring travelers which will accomplish the objects of the invention as hereinbefore stated. It is to be understood that various changes may be made in the arrangement and positioning of the parts without departing from the spirit of my invention. The invention is therefore limited only in accordance with scope of the appended claim.

What is claimed is:

In a spinning ring formed of an annular body, upper and lower annular flanges carried by said body, a supporting ring formed with an annular groove within which said lower flange engages, a traveler loosely engaging about said upper flange, an inverted U-shaped cleaning member having the legs thereof fixed in said supporting ring, the bight of said member being longitudinally curved and concentric to said spinning ring and disposed sub-' stantially coplanar with said upper flange, and an upwardly and outwardly inclined post carried by said supporting ring diametrically opposite said cleaning member and terminating at its upper end substantially coplanar with said upper flange and cooperating with said cleaning member in preventing accumulation of lint upon said traveler, said cleaning member and the upper end cfsaid posts being disposed spaced from the path of said traveler a distance such as to contact any lint clinging to said traveler and to thereby clean any lint from said traveler.
